Kimberly and Erika made some cheese croissants and vanilla croissants. Kimberly made 87 more cheese croissants than vanilla croissants. Erika made 135 more vanilla croissants than cheese croissants. The total number of cheese croissants made up 42% of the total number of croissants they made. How many vanilla croissants did they make altogether?

Number of vanilla croissants		Number of cheese croissants
58%		42%
Kimberly	Erika	Kimberly	Erika
1 u	1 p + 135	1 u + 87	1 p

Kimberly
Number of vanilla croissants = 1 u
Number of cheese croissants = 1 u + 87

Erika
Number of cheese croissants = 1 p
Number of vanilla croissants = 1 p + 135

Number of vanilla croissants in percent
= 100% - 42%
= 58%

1 u + 87 + 1 p = 42% --- (1)
1 u + 1 p + 135 = 58% --- (2)

(2) - (1)
58% - 42% = 135 - 87
16% = 48

1% = 48 ÷ 16 = 3

Number of vanilla croissants that they made altogether
= 58%
= 58 x 3
= 174

Answer(s): 174
